NOTES:
All table values referenced to maximum power from FCC type notification range and minmum efficiency values.
AC safety ground via third wire of mains inlets (PE green wire). AC safety ground should have unbroken connection back to earth post at mains
distribution panel. Threaded ground stud provided on rear of amplifier chassis for connection to rack buss-bar where required by prevailing safety norms.
EIA rack housing transmitter should be connected via copper strap to station RF ground. Connection should be via unpainted surfaces and
soldered/brazed for low resistance.
